What is the role of props (blocks, straps, bolsters) in yoga practice?

From training in therapeutic yoga I treat blocks, straps, and bolsters as tools to keep the nervous system calm while still benefitting from poses. Blocks under the hands, hips, or head shorten the lever, so the spine stays neutral and muscles can engage without compensating. Research on restorative practice shows that supported postures encourage parasympathetic nervous system response, lowering cortisol and heart rate, so I recommend bolsters for gentle backbends or reclined twists when the body needs a break. Straps act like extended arms when the joint capsule cannot reach full range yet, so you can keep the shoulders soft and the breath even while lengthening the hamstrings or moving into a bind. That lessens strain and makes it easier to stay in a posture long enough for fascia and nervous tissue to adapt. Encourage students to build trust in the props by experimenting with different heights or tensions, paying attention to sensations rather than chasing perfection. Keep a teacher or physical therapist in the loop if you have an injury so they can suggest specific setups and modifications.

Blocks under my hands kept balance steady, letting me breathe deeper without forcing hips or shoulders.
